Question :

Why is the flow of signals in a synapse from axonal end of one neuron to dendritic end of another neuron but not the reverse?Submitted on 23/12/2023 | Answered by Vandana Rana

Answer :

When it is transmitted to another neuron it takes the form of the neurotransmitter . Neurotransmitter are specialized chemicals . They enter the neuron only by a specialized channels . In dendrites such channels are present but absent in the axons .Neurotransmitters are able to enter the dendrites .

Because of all this the flow of signals in a synapse from axonal end of one neuron to dendritic end of another neuron and not in the reverse .
